Males/Mam wkxapm Patented July 22, 1952 TURBINEv QNSI f1" i surronr J'AN i) ooNN Charles ,D. Wilson. West Allis, Wis., assignor to This invention relates to; steam or other 8135?- tic'fluid turbines and more particularly toelastic fluid turbine .and condenser installations, and the principal'object of the invention is to provide new and improved elastic fluid turbine constructions and new .and improved turbine andjcondenser or'the-like installations.

- The iexhaust from an elastic .-fluid turbine is usually greceived-by-a condenser or other heat exchanger. 7 One of the objects of-rthe invention is ;to provide a construction wherein the base-' ment depth; or theamount the'installati'on extends below the floor levelyisreduced; that is, in particular, the lowest point'of the condenser," for example, is much higher than is the. case-with prior installations.

In known types of installation difficulty is experienced byreason of .the unequal expansion of the turbine and the condenser, so that the condenser must be supported frombelow bysprings. Furthermore, if the condenser contains a, large amount of water, the weight of this water puts an, added stress on the turbine by reason'of the fact that the condenser is hung fromthe turbine. Ac cordingly-,: another object-.of the invention is' the provision of a constructionywhich avoids these difllculties. p 1 v Other, objects will appear hereinafter as the description of the invention-proceeds.

The novel :features .ofthe invention: and how the objects are attained will appear moreifully from this, specification; andrthe accompanying drawing showingv one embodimentfof th'e invention and forming a part of this application;' and all these novel features are intended to' ,be pointed out, in the claims; i In the drawing: 1...: ;Fig..1 is aplan view of a steam-turbine and condenser installation embodying theinvention, some parts being'broken away" for the sake of clearness; i I

iolaims. (onto-95) operating'blading as-will be understood bythose I skilled in the art. a After the steam has passed through the blading (from right to left, as viewed in Fig. 1), it enters inside oi' the cylinder'an'd the outerperiphery of;

spindle being provided with the: usual coe an exhaust casing portion which is hereshown as comprising two portions 13;, extending laterally in opposite directions from the longitudinal center line of the turbine. The exhaust casing portions l3, l4 comprise a cover portion l5-which is here shown as integral with the upper half of the cylinder H, the cylinderbeing divided along a horizontal plane which includes thelongitudinal center line of the turbine; This horizontal plane, seen from the side of the installation, as in Fig. 2, is defined by a line It; and

vseen inthe section in Fig. 3, is defined by a line also designated l6.

The exhaust casing portions I3, 1- further comprise lateral extensions IT, [8 which are here shown as integral with. the lower half of the cylinder H. The lateral extensions l1, .l8 donot extend as far laterally as the cover portion [5 and terminate in generally U-shaped' upwardly open flanges 25,. 2 6, respectively, the outer surfaces of the flanges defining vertical planes 21, 28 (see particularly Fig. 3). Attheir upper sides the exhaust portions l1, l8 have longitudinally spaced flanges 35 and 36a, 361), the surfaces of which are in the horizontal plane IS. The

' flanges 36a, 3% merge with the horizontal flanges on the lower half of the turbine cylinder VII. The cover portion l5 has a flange 33 which is complementary to the 'flange'35 and bolted or otherwise suitably fastened thereto. The flange .33 merges with U'-shaped end portions 33a and 3312 which in turn merge with portions complementary to the flange portions 36a, 36b.

Disposed alongside of the exhaust casing portions 11, I 8 are condensers 30, 3|. These condensers may be of. any suitable internal construction (not shown) whereby the steam is caused to come into heat exchanging relation or fastened It will be upper half of the turbinecan enter the condenser through theopening provided within the heriaontaljoint between'theflanges 32a; 3311;

The flanges condenser through the opening provided within the vertical joint between flanges 34a, 25.

It should not be understood, however, that there is any distinct division between exhaust l steam coming from the upper and lower halves of the turbine, as it will be evident that the con denser 30 is connected to the exhaust casing por 'stallation, comprising: an elastic fluid turbine tion [3 by a joint in a horizontalplanel6, and

a joint in a vertical plane 21, these joints mutually communicating with each other; 1i The condenser is supported by support means disposed on opposite sides thereof this means being here shown as comprising atone side a steel-standard 40a engaged'at its 'top by brackets or feet Ma desirably integral with the condensershell, and at the other side by a concrete structure 42a engaged at its "top by bracketsor feet 43a desirably integral with the-condenser :shell. The support means just described serves to take'theweight of the condenser so that the weight of the condenser does not come on'the'flanges 32a and 25.

- The condenser 3!; is connected to'the exhaust casing portion it, and is supported similarly to the condenser 30 ashereinbeiore described,the parts being given the same reference numerals but with the sufiix b. V

The exhaust end of the turbine l O-is supported by means here shown as comprising a concrete structure which extends transversely of the longitudinal axis of the turbine 10 below a'bearing support? l The bearing support 5| is-integral with the lowerhalf l1, it of the exhaust casing. The foot of the bearing'support 51 engages the upper surface of the support means 56 directly or a'metallic pad (notls'hown) may be-interposed as will be understood by those skilled in the art. The plane of engagement of the-bearing support 5| with its support means 59 is the's'ame as'the plane of engagement of the feet Ma; 4311, 411), 4311 with their support means. r r The right hand end of the turbine [0 maybe supported in a conventional or any suitable manner asiwill be understoodrby those skilled in the artrj The bearing support 5! contains a bearing for a shaft drivenby the spindle I2, and as here shown'ithe shaft isadapted to drive an'electri'c generator 56 which may be supported by the'sup- Theupper surface of the" support means' for the turbine and condensers'as hereinbefore'de scribed may be-taken-as the floor line for the in+ stallation; this beingfindicated by the line-Sll It :will be evidentsthat the invention materially reduces the necessary basement depth,'andthat the hereinbefore ,mentioned ldifliculties' are obviated. It is to be noted in particular that the condensers are not hung from the turbine casing but areseparately supported, and, more particularly, are supported at 'the' same .level'as'is the turbine casing. The condensers are hung free of the basement floor, and no supporting springs are required; i i; From'the ioregoing it will beapparent'to'th'ose skilled in the art thatthe'illustrated embodiment of the invention provides: new and improved v inaverticalplaneh the spirit of the invention, or sacrificing all of the advantages, thereof, and that accordingly the disclosure herein is illustrative only, and the invention is notlimited thereto.
